Benefits of technology
"The invention is a system that includes a movable subsystem and a structure. The movable subsystem has an electrical component that provides electrical signals with information, a source of electromagnetic radiation, and a modulating component that modulates the source of electromagnetic radiation to create the information through the use of electromagnetic radiation. The system also includes a receiving subsystem that receives the electromagnetic radiation and converts it into other electrical signals. The technical effect of this invention is the ability to provide a system that can transmit and receive information through the use of electromagnetic radiation."
Problems solved by technology
In applications where the data rate of the information being transferred between the two subsystems is high, the presence of a long cable can result in signal degradation and the cable itself to serve as a source of radiofrequency interference, either by transmitting or receiving radiofrequency interference.
The continued motion of the cable can also result in quality problems.
Furthermore, although in recent years there has been significant effort in reducing the impedance of connections, there are practical (such as cost) and physical limits to the decrease in the impedance of connections.

Methods and systems for transferring information between a movable system and another system. The movable subsystem includes an electrical component providing electrical signal including information. Electromagnetic radiation is modulated according to the information. The other subsystem includes a receiving component that receives the modulated electromagnetic radiation and converts the received electromagnetic radiation into other electrical signals.
Description
BACKGROUND OF THE INVENTION[0001]Many systems (such as, for example, scanners, printers, and recording devices) include, within the system enclosure, a movable subsystem and another subsystem, where the two subsystems transfer information.[0002]A typical example is the image acquisition subsystem in a scanner and the processing subsystem. In such an example, the image acquisition subsystem includes an image acquisition device that acquires a scanned image. The scanned image data has to be transferred to the processing subsystem. However, typically the image acquisition subsystem moves over the item to be scanned. In conventional systems, a flexible cable connects the image acquisition subsystem to the processing subsystem. In applications where the data rate of the information being transferred between the two subsystems is high, the presence of a long cable can result in signal degradation and the cable itself to serve as a source of radiofrequency interference, either by transmitt...
